TYPE-WRITING IVIACHINE.

To. all whom it may concern:

Be it known that I, GEORGE A. Sam, citizen of the United States, and resident of Ilion, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

My invention relates to typewriting ma chines and more particularly to tabulator mechanism of thecharacter disclosed in the application of Oscar Woodward, Serial No. 565,846, filed June 8, 1910. In the mechanism disclosed in said Woodward application, a series of column stops are cammed back to. inoperative osition by a resetting cam, and the main o ject of my present invention is to provide simple and eilicient means for resisting undue StI illIl on the ficient number of the construction as a Nielsen Serial column stop bar when the column stops are being cammed back to inoperative position.

To the above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangements of parts, and combinations of devices to be hereinafter described, and particularly pointed out in the appended claims.

In the accompanying drawings, wherein like reference characters indicate correspending parts in the various views, Figure 1 is'a fragmentary side elevation with parts in section of one form chine embodying my invention; only a sufparts being shown to illustrate my invention in its embodiment therein. Fig. 2 is a fra mentary plan View of the same with parts broken away.

The general purposes to be attained by Whole shown in the no companying drawings, are the same as those attained in the application of Sivertsen & No. 488,675, filed April 8th,

1909 and in the application of Oscar Woodward hereinbefore referred to, my invention bodied in various being confined to the embodiment of the resisting bracket 36 in combination with devices shown in the Woodwardapplication, for example. I have illustrated my invention in the present instance embodied in'a No. 11 Remington machine. It should be understood, however, that the invention may be emstyles ollgtypewriting machines.

Patented Oct. 4, 191G Serial No. 565,948.

The frame 1 of the machine supports a carriage 2', which is adapted to travel from side to side of the machine over the to plate thereof; the carriage being snpporte on anti-friction balls or rollers 3. The carriage supports the usual cylindrical platen, conventionally represented in the present in- Rearwardly extending bracket arms l are fixed to the carriage at 5 and support a column stop bar 6, which extends throughout, or substantially throughout, the length of the carriage. This bar is provided with teeth on the upper and lower sides thereof, with interdental spaces between said teeth for the reception of bifurcated column stops 7, which are adapted to slide'fore and aft of the machine in said interdcntal spaces and into and out of operative position. The stops 7 are adapted to be held against accidental displacement from the operative or inoperative positions by frictional. en 'agement between said stops and the co umn stop bar, or by the use of suitable friction springs. There are preferably as many pairs of interdental spaces in the column stop bar as there are letter space ositions of the carriage in its travel from si e to side of the machine, or as there are indices on the carriage scale, with which a fixed pointer 8 is adapted to cooperate. Each column stop has an upwardly extending stud 9 thereon adapted to cooperate with a bar 10 arranged above the column stops, and fixed at 11 to the column stop bar. The bar 10 limits the rearward movement of the column stops on the column stop bar 6 and prevents a removal of the stops therefrom, except when the bar 10 is detached.

Denominational stops 12 are adapted to cooperate with the column stops Which are projected to operative position. The denominational stops are each formed as a part of an upright denominational stop lever 13, pivoted at 14 to a tabulator frame 15, secured to the frame of the machine b screws 16. The lower. end of each denomr national stop lever is connected to a link 17, which in turn is connected at its forward end to an angular lever 18, pivoted;

on a pivot rod 19 fixed to the frame of the machine. 'labulator keys 20 are operatively connected to the angular levers, toactuate them and efiect a forward movement of the corresponding denominational stops into the path of the operative column stops 7 Restoring springs 21 are each connected at one end to an angular lever 18, and at the opposite end to a guide plate 22 for the stems of the tabulator keys.

The different column stops are projected to operative position by selecting mechanism, which comprises an upright arm or finger 23; the contact end or portion of which is of sufiicient width to cooperate with but one column stop at atime. The member 23 is rigidly connected to a rock shaft 24 mounted to turn in a bracket 25 secured to the to plate of the machine. A rearwardly exten ing crank arm 26 is secured to the rock shaft 24, and has a depending link 27 connected thereto. The lower end of the link 27 is connected to a key lever 28, fulcrumed at 29, and connected to a restoring spring 30. The key lever 28 carries a selecting key 31, which is arranged in the keyboard of the machine. A depression of the selecting key 31 effects a rearward movement of the finger 23, thus movin the column sto 7 WlllCh is in register therewith, rearwar 1y to operative position. When pressure on the key 31 is released, the spring 30, restores controlled thereby to normal position.

It will be understood that the particular column sto to be selected depends on the position 0 the carriage relatively to the selecting device or finger 23; the column stops being successively brought into register with said finger during the travel of the carriage.

In order to restore the various column stops to operative position, I have provided a cam 32 which is formed on a carrier or slide 33, adapted to move fore and aft of the machine and into and out of cooperative relation with the operative column stops. The cam 32 is provided with oppositely inclined cam faces 34, either of which faces is adapted to cooperate with the column stops; depending on the direction of travel of the carriage, and to cam the column stops forw'ardly to inoperative position. The cam 32, in its movement into and out of cooperative relation with the operative column stops, is controlled by a finger piece 35. The cam 32, its slide 33, and the finger piece 35, are all carried on the tabulator frame 15, which is fixed to the frame of the machine and may, for the purpose of the present invention, be regarded as a part thereof. The means by which the finger piece 35 is rendered efl'edtive to control the movement of the cam 32, and the construction of said cam and its slide 33, may be the same as those disclosed in the Woodward application hereinbefore referred to, and further detailed description of these parts is deemed unnecessary. It is sufficient, for the purpose of the present invention, that it be understood that a depression of the the key and the parts finger piece 35 is effective to move the cam 32 from the fullto the dotted line position in Fig. 2, and that a relative movement between the carriage and the cam at this time is effective to cam the operative column stops forwardly on the column stop bar, to inoperative position.

It sometimes occurs, especially on long carriages, that the camming of a considerable number of the operative column stops forward to inoperative position, unduly strains the column stop bar and tends to flex the same forwardly. In order to resist any undue flexing of the column stop bar, and to resist any undue strain thereon, I have provided a rigid bracket, or resisting device 36, which is secured by screws lato'r frame. This bracket extends forwardly over the column stop wardly as at 38 in front of the column stop bar and then rea-rw'ardly as at 39. The free end of the part 39 is adapted to just clear the forward face of the column stop bar so that if the column stop bar should be flexed forwardly,,during the camming forward of the column stops on the bar, it would be brought into contact with the fixed bracket which latter would resist further flexing movement of the stop bar, and resist any undue strain thereon. It will be seen that the part 39 of the bracket is received between the arms of the series of bifurcated column stops and that the bracket in no manner obstructs the free movement of the carriage from side to side of the machine. 7

What I claim as new and desire to secure by Letters Patent, is

1. In a typewriting machine and tabulating mechanism, the combination of a stop bar, a series of stops mounted on said stop bar for movement into and out of operative position, means for moving the stops on the stop bar, means independent of but cooperative with said stop bar to resist straining the bar when said stops are being moved on the bar by said stop moving means, and a key controlled stop cooperative with said first mentioned stops.
